[0002] In the production and quality detection process of a watertight connector, the plugging force of the jack is a crucial performance indicator. The traditional testing method is generally a direct stretching method. To avoid the gauge from falling down during testing, the gauge is clamped by the jack and then lifted up, thereby driving the counterweight block, so that the bottom of the gauge and the counterweight block are in interference fit. When repeatedly clamping and testing, the gauge and the counterweight block need to be repeatedly disassembled, which causes wear of the counterweight block, and thus the interference fit effect of the counterweight block and the gauge is lost. In view of this, the present application is proposed. SUMMARY

The clamping part protrudes from the second counterweight block. The jack cooperates with the clamping part.
[0006] Further, the limiting device comprises a limiting block and an elastic member. The limiting block is slidingly arranged on one side of the first counterweight block away from the groove. The elastic member is arranged between the limiting block and the first counterweight block.
[0007] Further, the inside of the jack is hollow.
[0008] Further, one side of the jack in contact with the clamping part of the gauge is symmetrically provided with a rectangular groove.
[0009] Further, the upper part of the second counterweight block is disc-shaped, and the lower part is a plurality of supporting cylindrical columns.
[0010] Further, the height of the cylindrical column of the lower part of the second counterweight is higher than the height of the second counterweight.
[0011] Further, the upper part of the second counterweight is in the shape of a disc with a circular hole in the middle, and the diameter of the circular hole is smaller than the diameter of the first counterweight.
[0012] Compared with the prior art, the utility model has the beneficial effects including:
[0013] By setting the limiting column and the limiting device, the tooling can take out and connect the needle gauge by itself, and the problem of abrasion of the first counterweight caused by repeated clamping due to the interference fit between the needle gauge and the first counterweight in the traditional testing method is avoided.

[0022] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is further explained in detail below in combination with specific embodiments and referring to the drawings.It should be understood that these descriptions are only exemplary, and not to limit the scope of the utility model.In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0023] Please refer to the accompanying Figures 1-5 Water-tight connector jack plug-in force test special tool, including first counterweight 1, through hole 2, groove 3, needle gauge 4, limiting device, jack 6 and second counterweight 7, through hole 2 is set up on first counterweight 1, the middle of through hole 2 is circular, both sides are U-shaped, needle gauge 4 passes through the through hole 2 on first counterweight 1 and second counterweight 7, groove 3 is arranged at the bottom of first counterweight 1, the upper portion of second counterweight 7 is disc-shaped, the lower portion is a plurality of supported cylindrical column 9, the height of cylindrical column 9 in the lower portion of second counterweight 7 is higher than the height of second counterweight 7, the disc-shaped upper portion of second counterweight 7 is provided with a circular hole in the middle, and the diameter of the circular hole is smaller than the diameter of first counterweight 1;
[0024] Needle gauge 4 includes support part 8, column 9, clamping part 10 and limiting column 5, support part 8, column 9 and clamping part 10 are sequentially connected, limiting column 5 is arranged on column 9, needle gauge 4 and limiting column 5 pass through through hole 2, support part 8 and groove 3 cooperate, clamping part 10 extends out of second counterweight 7, jack 6 and clamping part 10 cooperate.
[0025] Firstly, the clamping part 10 of needle gauge 4 passes through the through hole 2 on first counterweight 1, the special design of through hole 2, the middle circular, both sides U-shaped, allows needle gauge 4 to pass through the initial position smoothly, and the U-shaped part reserves space for subsequent rotation operation, when the support part 8 of needle gauge 4 reaches the bottom of through hole 2, the support part 8 will abut against the groove 3 at the bottom of first counterweight 1, to ensure that the needle gauge 4 is lifted upward to drive the first counterweight 1 to rise synchronously, then, the needle gauge 4 is rotated 90 degrees around its axis, at this time, the limiting column 5 on the needle gauge 4 and the shape of the column 9 no longer match the shape of the through hole 2, forming a locking state, preventing the needle gauge 4 from falling off the first counterweight 1, then, the second counterweight 7 is placed above the first counterweight 1,
[0026] At this time, the jack 6 is first pressed inward to enhance the clamping effect, and then through the cooperation of the jack 6 and the clamping part 10 of the needle gauge 4, since the diameter of the circular hole on the second counterweight 7 is smaller than the diameter of the first counterweight 1, when the needle gauge 4 is lifted through the jack 6, the first counterweight 1 rises to drive the second counterweight 7 to rise together, realizing overall lifting for subsequent plug-in and pull-out force test. By setting the first counterweight 6 and the second counterweight 7, the weight of the first counterweight 6 guarantees the lower limit of the plug-in force, and the weight of the second counterweight 7 guarantees that the plug-in force does not exceed the required upper limit.
[0027] In some embodiments, the limiting device includes a limiting block and an elastic piece, the limiting block is slidingly arranged on the first counterweight 1 away from one side of the groove 3, and the elastic piece is arranged between the limiting block and the first counterweight 1.
[0028] Before the needle gauge 4 needs to be rotated by 90 degrees, the limiting block is moved downward, the elastic piece is compressed, then the needle gauge 4 is rotated, after the rotation is completed, no force is applied to the limiting block, and under the resetting action of the elastic piece, the limiting block moves upward, in detail, the number of the limiting blocks is four, and the four limiting blocks limit the two sides of the limiting column 5 respectively.
[0029] In some embodiments, the inside of the jack 6 is hollow, and a rectangular groove is symmetrically opened on one side of the jack 6 in contact with the clamping part 10 of the needle gauge 4.
[0030] The inside of the jack 6 is hollow, which facilitates insertion and wrapping of the clamping part 10 of the needle gauge 4, and a rectangular groove is symmetrically opened on one side of the jack 6 in contact with the clamping part 10 of the needle gauge 4. This design not only increases the contact area of the jack 6 and the clamping part 10, improves the stability of clamping, but also allows the jack 6 to have a certain elastic deformation when subjected to pressure, better adapts to the shape of the clamping part 10, and ensures that the needle gauge 4 will not be damaged due to friction during lifting.
